What COREUTILS_CLEANUP_BIN is doing is not to install a symlink
between /bin/foo and /usr/bin/foo. Indeed, such a symlink is not
necessary: both /bin and /usr/bin are in the PATH, so having /bin/foo
and /usr/bin/foo is totally useless.

What COREUTILS_CLEANUP_BIN does is to make sure that in a
non-BR2_ROOTFS_MERGED_USR case, the symlinks to coreutils are installed
in the same location as the corresponding Busybox applets, so that we
properly handle the conflict between Busybox applets and full-blown
variants, as I explained in my reply to your comments on PATCH 1/2.

Best regards,

Thomas
